It’s no secret that electric range ovens are one of the most essential kitchen appliances. This is primarily because ovens have higher usability– you can do every task from reheating to cooking and baking.
Ovens also make preparing delicious snacks like popcorn easier and faster.
Since ovens are used so frequently and cost a good amount of money, it’s always advised to get electric ovens from trusted brands like LG.
However, that doesn’t mean your oven won’t run into a problem after some time- LG Electric range oven touchpad buttons not working has become a common concern.
Luckily, there are various solutions that you can try to solve this issue and get your oven working efficiently again.
LG Electric Range Oven Touchpad Buttons Not Working
1. Control Panel
When the buttons on the touchpad don’t work, your first consideration should be checking the control panel. This is because when the control panel gets defective, it will lead to issues in the buttons’ functionality.
If you want to check the control panel, you need to press all the buttons.
If some buttons are working while some aren’t working, you just have to get the control panel repaired (you won’t have to get the entire touchpad replaced) by LG technicians or other licensed professional technicians.
If you’re hiring a technician online, there are a few measures you can take. Always be upfront and ask about their experience working with LG ovens, as each brand carries different models with different repair parts.
Make sure the technician you hire is licensed and has proper credentials. This will help you avoid losing the warranty on your oven (if you recently bought it).
In addition to this, read the online reviews on the repair technician’s profile. Paying a little extra for a technician with stellar reviews will likely get you the best service, and that is always worth spending extra money on.
2. Membrane Switch
When the touchpad buttons stop working, the second reason could be the membrane switch. The membrane switch is generally called the touchpad and is often connected with the soft-touch switches (these are electrical switches).
The membrane switch has a conduction coating which might wear out or get damaged due to repetitive usage. The power button is more prone to wearing out, but certain buttons for functions used daily can become hard to run as well.
For this purpose, you need to switch off the oven and take out the cabinet. Then, use the multimeter for checking the continuity. If the multimeter doesn’t show resistance on the display, the membrane switch needs a replacement.
Membrane switches can also be temporarily repaired- repair kits for membrane switches are available online. These contain silver-based paint pens but fail after some time. Replacement is a permanent solution.
You can also replace the touch membrane switch with push buttons as those last longer, especially if you have an old oven and don’t have to worry about LG’s warranty policy.
Your technician can give an expert opinion on whether or not a push-button switch is better or not.
3. Child Lock
If all buttons are not working on the touchpad, it might be because the child lock is enabled on the LG electric range oven. These ovens generally have to be protected from the kids to ensure there are no accidents.
So when the child lock is switched on, the touchpad buttons won’t work, so kids cannot operate the oven.
To switch off the child lock, you need to find the stop and start buttons on the touchpad. Every oven model has a different design, so there’s no set location for these. To deactivate the child lock, first, press the stop/clear option.
Then hover to the start/enter option, press, and hold for 3-4 seconds. An L or lock icon may appear on the screen. After releasing, press and hold the same start/enter button for 3-4 seconds more. The lock or L should disappear.
If this symbol doesn’t appear in the first place, then refer to your manual and see what the child lock display looks like. If there’s no indicator for child lock, then there’s some other issue.
You can troubleshoot this using our extensive guide, so keep on reading.
4. Touch Sensitivity
When the touchpad buttons don’t work on your LG range oven, there are chances that the touchpad area is unclean. So, first of all, you should clean the touchpad area and make sure it’s free from grease.
Use a soft and damp towel-like dishcloth to clean the area, then use a dry cloth to wipe the moisture. Always avoid using harsh cleaners and chemicals to cut the grease.
Simple dishwashing liquid should suffice. Always keep the touchpad dry using a cloth- a dry touchpad is more responsive.
5. Cold Reset
This is the last option that you can try when touchpad buttons don’t work. The cold reset is pretty simple as you just have to switch it off for thirty minutes and the reset will be performed.
It’s one of the most effective ways of resolving the touchpad button issue and can fix some other technical issues like lack of heating too. Remember that a child lock can activate after resetting sometimes, so go through the unlocking steps we mentioned before.
6. Control Board
If all solutions have failed and the buttons on the touchpad aren’t working, there are high chances that the control board has gone bad.
If you touch the touchpad but it doesn’t respond but the lights switch on, the control board is the main culprit. Another sign of control board damage is when the display keeps changing, and you hear different beeping sounds every time.
The control board is designed to generate low-voltage which is supplied to the touchpad. When the control board isn’t able to generate the low-voltage power, it needs a replacement to ensure the touchpad is properly powered up.
Internal wiring failure, tripped house circuits, and malfunctioning power cords lead to this control board damage. Having your oven plug in a socket where it’s loose and not fixed properly can also cause this damage.
Avoid repairing the control board yourself and get a licensed technician to do the fix.
What If The Touchpad Light Is Off?
Sometimes, the touch functions may work properly but you won’t get a full timer or temperature display, which can make cooking and baking a little confusing.
All electric range ovens have at least one light inside them to show you the oven space and light in the top touch panel with all the functions. Working lights help you keep a check on everything going on inside the oven.
However, as ovens get older, so do the lights. After some time, they may stop working properly. While you can still operate the oven, not seeing the display properly can be an annoyance.
When lights are out, the problem may be in the light itself, or the socket/assembly.
You can determine whether the light has turned out with a multimeter and ensure the power supply is intact. You simply need to replace the LED if only the light is troubling. If you can’t seem to diagnose the issue, find a technician to help.
The Bottom Line
While the LG electric range ovens are versatile in function and offer efficient cooking, they may run into some touchpad problems, where buttons may not work properly or the display lights may go out.
Touchpad buttons not working can be resolved by following our detailed guide and troubleshooting every issue.
Sometimes the problems are basic enabled features like child lock while other times they’ll be wear and tear like worn-out membrane switch. These require repairs and replacement.
And in the end, if you can’t figure out what’s wrong with your oven, then calling an LG technician is your best bet.
